CTS Electrocomponents 194-2MS DIP Switch - Equivalent & Substitute Parts

Part Overview

The CTS Electrocomponents 194-2MS is a through-hole DIP switch with SPST circuit configuration, rated for 50mA at 24VDC. This component is designed for applications requiring manual switching functionality with a piano-style actuator. The part is currently active in production and widely available in inventory. Substitute parts may be required due to supply constraints, design revisions, or application-specific parameter requirements that exceed the original specification.

Key Parameters

Substitute Part Grouping Explanation

The Grayhill Inc. 76PSB02T qualifies as a functional substitute for the CTS 194-2MS based on the following alignment of critical parameters:

Both parts share identical circuit topology (SPST, 2-position), actuator design (piano-style, raised), mounting configuration (through-hole, right-angle), and pitch spacing (0.100"). Both maintain gold-plated contacts, operate across the same temperature range (-40°C to 85°C), and comply with ROHS3 and REACH requirements.

The 76PSB02T provides enhanced electrical performance with higher current rating (150mA versus 50mA) and voltage rating (30VDC versus 24VDC), making it suitable for applications requiring greater switching capacity while maintaining mechanical and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CTS 194-2MS and Grayhill 76PSB02T are active production components with full ROHS3 compliance and REACH unaffected status, making either suitable for regulated applications. The selection between these parts depends on application current and voltage requirements.

The CTS 194-2MS is appropriate for circuits operating at or below 50mA and 24VDC. The Grayhill 76PSB02T accommodates higher switching loads up to 150mA and 30VDC, providing design margin for applications with potential current or voltage transients. Both parts maintain identical mechanical footprints and environmental operating ranges, ensuring PCB layout compatibility.

The CTS 194-2MS demonstrates higher electrical life (7,000 cycles versus 2,000 cycles), which may be relevant for high-cycle switching applications. The Grayhill part exhibits slightly lower height above board (0.301" versus 0.311"), a minor consideration for space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the Grayhill 76PSB02T directly replace the CTS 194-2MS on an existing PCB?

A: Yes. Both parts share identical mounting type (through-hole, right-angle), pitch spacing (0.100"), and actuator configuration (piano-style, raised). The height difference (0.010") is negligible for most applications. Verify that your circuit design does not depend on the lower electrical life rating of the Grayhill part.

Q: What are the primary differences between these two parts?

A: The Grayhill 76PSB02T provides higher current capacity (150mA versus 50mA) and voltage rating (30VDC versus 24VDC). The CTS 194-2MS offers longer electrical life (7,000 cycles versus 2,000 cycles). Both maintain identical circuit topology, temperature range, and compliance certifications.

Q: Are there any packaging or inventory considerations?

A: Both parts are supplied in tube packaging and are currently in active production with substantial inventory availability (928 pcs for CTS 194-2MS; 899 pcs for Grayhill 76PSB02T).

Q: Do both parts meet regulatory requirements for my application?

A: Both parts are ROHS3 compliant and REACH unaffected. Verify that your specific application requirements do not exceed the electrical or mechanical specifications of either component.

Q: Which part should I select for a new design?

A: Select based on your circuit's actual current and voltage requirements. If your design operates below 50mA and 24VDC, either part is suitable. If your design may experience higher transient currents or voltages, or requires design margin, the Grayhill 76PSB02T is the appropriate choice. For applications requiring maximum cycle life, the CTS 194-2MS is preferred.
